Kernel compile - encountering issues with Makefile script

[Republicus]

I'm having a heck of a time trying to patch the kernel, which I am doing to support eth_ipoib.

It seems I am missing a package, a problem with the kernel's Makefile scripts, or I'm missing a few screws... It's driving me there, anyway.

So I am working in the path:

/usr/src/linux-headers-5.0.18-1-pve/

I've applied my patches and now ready to compile:

make -j8 deb-pkg LOCALVERSION=-custom

ERRORS encountered:
(1) no file at /fs/aufs/magic.mk

scripts/kconfig/conf  --syncconfig Kconfig
  UPD     include/config/kernel.release
make clean
  CLEAN   .
fs/aufs/Makefile:3: fs/aufs/magic.mk: No such file or directory
make[4]: *** No rule to make target 'fs/aufs/magic.mk'.  Stop.
make[3]: *** [scripts/Makefile.clean:88: fs/aufs] Error 2
make[3]: *** Waiting for unfinished jobs....
make[2]: *** [Makefile:1402: _clean_fs] Error 2
make[2]: *** Waiting for unfinished jobs....
make[1]: *** [scripts/package/Makefile:70: deb-pkg] Error 2
make: *** [Makefile:1443: deb-pkg] Error 2

I installed all of the aufs packages i saw in the package manager

apt-get install aufs-dev aufs-dkms aufs-tools

This didn't immediately resolve the issue, but I noticed aufs sources at /usr/src/ so I created a symbolic link where it was missing in the linux-headers

ln -s /usr/src/aufs-4.19+20190211/fs/aufs/magic.mk magic.mk

This allowed the script to move forward

(2) no file at Documentation/Makefile

  UPD     include/config/kernel.release
make clean
scripts/Makefile.clean:15: Documentation/Makefile: No such file or directory
make[3]: *** No rule to make target 'Documentation/Makefile'.  Stop.
make[2]: *** [Makefile:1402: _clean_Documentation] Error 2
make[2]: *** Waiting for unfinished jobs....
make[1]: *** [scripts/package/Makefile:70: deb-pkg] Error 2
make: *** [Makefile:1443: deb-pkg] Error 2

scripts/package/Makefile:127: *** missing separator.  Stop.
make: *** [Makefile:1443: deb-pkg] Error 2

touching the missing file gets the script moving forward again.

mkdir Documentation && touch Documentation/Makefile

3) TAR commands

make clean
/bin/bash ./scripts/package/mkdebian
  TAR     linux-5.0.18-1-pve-custom.tar.gz
tar: COPYING: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors
make[1]: *** [scripts/package/Makefile:72: deb-pkg] Error 2
make: *** [Makefile:1443: deb-pkg] Error 2

From here I cannot make out whats wrong.

@ line 72:

        $(call cmd,src_tar,$(KDEB_SOURCENAME))
        origversion=$$(dpkg-parsechangelog -SVersion |sed 's/-[^-]*$$//');\
                mv $(KDEB_SOURCENAME).tar.gz $(KDEB_SOURCENAME)_$${origversion}.orig.tar.gz
        +dpkg-buildpackage -r$(KBUILD_PKG_ROOTCMD) -a$$(cat debian/arch) -i.git -us -uc

I am desperate to get eth_ipoib working and your your help in this matter would be greatly appreciated.

I took the current OFED from Mellanox and ran configure --with-e_ipoib-mod and then make. I didn't test its function, but it did properly load (kernel 5.0.18-1).

Thanks for answering Alwin. Do you mind telling me which version/distribution you downloaded? I have tried the latest source for Debian 9.6 but in it find no Makefile.

The OFED version I used, was the 4.6, you can check for Ubuntu's (will be same OFED version as Debian), as our Kernel is Ubuntu based. Unpack the source package and the corresponding kernel package (eg. mlnx-ofed-kernel-4.6/). There you can find the eipoib module.
